To all whom, it' may concern,.-

V Be it known that I, LOUIS PFINGST, of

Dorchester, Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in P owerBrakeS, ofwhich the following is a specification.

Mfr invention relates to limprovements in Y power-brakes, and especiallyto brakes which 1o are ladapted to be applied by motive powerl Jfortransmitting motive power to the chain--k winding brake-spindle; tolprovide an varrangement for automatically engaging the 'motor-powerclutch members by an electric '1 circuit;to. provide an arrangementforcut- 3o ting out `the .clutch .memberscircuit by anotherelectriccircuit or by manual operation; to automatically cut in the currentflowing tothe motor to rotate same; to cut out said Current by manualeffort, so that in case' thel motorman desertshis car lforany reason thebrakes will befautomatically applied, and by this lautomatic.arrangementl a plurality of spindles can be Set in motion to .set thebrakeson one or more cars. These y4c and other objects are accomplishedbythe fmechan'ism hereinafter described and shown. f My inventionconsists of' certain novel features'hereinafter described, andparticularly pointedout in the Claims.

Fast on the motor-shaft C is a driving clutch member D', and located insuitable recesses on the exterior of the clutch member D are two bandsof brass D2 D3, which are suitably connectedto the ends of Thecircuit-closing bracket/ E is supported by the upright arm B3 ofthebell-crank lever B3 and carries the 'upper and lower contact-wheels EE2, suitab y Insulated from the bracket, as shown, .the wheel E2 actingas an inlet and the wheel E acting as an outlet, ythereby forming anelectric clutclncircuit-closer.

E3" is a magnetic solenoidattached to the base-frame, which cooperateswith the metal pin. B7, pivoted on the arm B3, and can be actuated'.when the magnetic wire is ener-y gized. The energizing of said wireis` accomplished bythe switch'E3 being closed by the olperatorlacing his-footon the-inner part of t e trea E3, which will operate the lever-'arm'B3, pivote'd at E3 to the'lever B2. The extreme end E7 lof theleverarm B3 is insulated, as shown, so `as to prevent the current.passing oil and compel it to pass through the wire 7 in t'the'rnagneticsolenoid E3 and thence outlto the ground. by the Wire 8.thisoperationthe upright -arm B5 of the bel cran-k lever B2 is ulledaway from the magnetic clutch mem `er D', breaking the electric contacton-the bands D2 D3. This will deenergize themagnetic clutch, allowingthe lower clutch member D to separate from the upper .member D bygravity. With the clutch members in this released position the operator`canrotate vthe-'motor-armature C or allow itv tostand still at'will. Itwill be understood that when Ithe' mechanism is inv this. releasedposition the motor is running free and is not a'ctingvupon thespindle`C3, as no motion is communicated to the gear C..

.The o eration of the switch E4, as ,above describe will when suitablyconnected by the wire-circuit cause the operationof a plurality ofmotors and spindles o n the dit-v ferent cars for train service. i

Itv will be'further understoodthatthis operationwill release one or allof the brakes by the operation of one or a' plurality of motormechanisms located on one or a plurality of cars comprising a train F isan enlarged diameter of the motor base-frame B, forming a socket for thein. sertion. of the lower end of the motor-frame F. and secured bysuitable bolts F2 and bolts F3, which latter pass through.I themotorfra'me C tothe -pole-pieceFj, (see Figs. 5 and 65,) securing allman assembled positron.

.H5 is a boss formed on the under side of Vthe top of theextension-frame G, forming an upper .bearing for the motor-armatureshaft C.

H3 H7 are insulating-bushings for the purpose of insulating thebrush-holding brackets H3.

:H3 is a metal washer between the bushing H7 and the jam-nut H10, saidnut meshing with the thread H11 on the lowerend of the boss H5. This nutH10 is used for the purpose of fastening the brush-holding arrangementin 'a Aiixed position' after the brushes are set. The' brush-holdingarms J J are secured tothe bracket H3. The brushes K K make contact withthe eommutator K2.

On the upper end of the motor-armature shaft C andwithin said cap is ixed the ratchet dog or clutch K5, engaging with thecompanion ratchet member or dog K3, which is held from rotation by thebolts K7 passing through the walls of cap K3, the points of which iit inslots on the companion member K3'y and allow a vertical movement of saidmember K". This member K6 is held in engagement with the member by thespring K3, interposed between the under side of the cap K3 and the topof the member K". The

G3 is a boss on theltop of the extension-- frame G, forming with thehole G3 a guide and bearing for the upper end of the brakespindle C3.

,L is a motor-armature havingits arma-v tureshaft provided with extendedends, as show1r,'wl1ich are journaled in the boss B4 and boss H5.

By the aboveid'esc'ribed construction the motor-armature is held inplace. j The-loose. clutch member D is connected to 'the gear C, forminpart thereof, 'by means of the throat C, an said member is ada ted toalver-tical movement' on the loweren .of the motor-armatureshaft C. On theupperj end of the `brake-spindle C3 is mounted a lhand-power handleprovided withmechanism' to permit the s indle C3 to rotate freely in thechamber M o saidhandle when the spindle isdriven by motive-powerwi'thbutturning the handle M'. Normally 't e' v hand-le M is disengaged from'the brake-spindle C3. To engagesaid handle when desired to operate thespindle 55 by the. wire 5, thence to the' brush K', to the aaneen byfhandower, the operator, placing his f hand on-7te'top 'of the handle,will depress -t 'ough be conveyed to 'the bell-crank lever M5, which theplunger M2 against thel resiliency oi the s" ring M 'housedv in thehandle M, and the rod-M4 a downward pressure will ,i's'pivoted on theforked bracket M1", termed onflthe underv side of the handle M, causingthe other end ci the bell-crank lever to move inwardly toward thebrake-spindle, pressing on-the plunger M7, which is 'driven into one ofVthe orifices M8, formed on the nxed hub M ci neet the handle 'from thespindle, the operalshaft N'-, supported by the brackets i 2 and thebearing N3 'end thereis mounted the handle N4,

ytor releases the pressure from the plungerM2 and springs M3, withdrawsthe pin M7 from the-spindle-hub M5, leaving the brake-spin.- dle Ma freeto be revolved without the handle bythe motive power.

Themotor current-controller N consists of a in the frame G, and on itsupper which y can'be removed, if desired'. This handle i 4 isarranged-to rotate the shaft N' against the spring N5, secured at oneend ,at N6 to the ,frame G and attheother end to the shaft N Mounted ator near the lower end of the shaft N'- is the contact-arm NS, whichsuports the contact-plate'N", which is insulated om it bythe strip O:Directly opposite on the hub of said arm is Jformed the quadrantratchetcircle P, with which coperates the awl P', pivoted on the bracket P2 bythe pin 3.' The ratchet-circle and the pawl are for thepurpose-'ofholding the contact-arm' N8 out of thefelectric circuit whennot in use. A The bracket Q is secured to the frame G by suitable boltsand carries the terminal posts -R R', suitably insulated, as shown, fromthe bracket Q.; The intake-wire Iv is connected with the post R, and theintake-wire 2 is convnected with the postV R', receiving current fromthe trolley-wire when the contact-plate WN covers both, after which thecurrent will 'low through the Wire 2, insulated from the post R',

to the motor lield-wire 3, which is a continuation .of the wire 2, andthe circuit then passes into the field-coils 4, Fig. 5,

wind up the chain C4 thence to the brushlholding arrangement J' throughthe brush K the wire to the ground'.l Theoperation of rotati to' applythe. brakes .on

` one vor more cars is as follows: The operator disengages the pawl P'from the quadrant- "ratchet circle P 'from the position shown in Fig.'2, when the spring N5-Will cause the fopng the Spindle c? w" erator touse pressure on the end N4 to 'keep the contact-plate N from closing thecircuit. At will the operator may release said pressure on the4 handleNtfwhen the' spring lN5 will automatically act to cover V the binding-`posts R R' by the plate N9, whichwill close lthe circuit tri allow thecurrent to ilo-w from its source'across the plate N to the post R',thenceto the wire 2, to the wire 3(which isa continuation ol the wire2,) passing through the fields 4 thence to the wire to the brushholdingarm d" passing out through theI brush K' to the commutator K2, throughthe brush K to the arm J, and te the groundy by the wire 6. This ilowofcurrent will rotatel the' armature L and the extended arn'iatiire-Vvshafts C, which will rotate the clutch member D'. N ow to operate thespindle C3 to apply the brakes the operator breaks thel circuit throughthe switch E by releasing the pressure on the tread E5, and the spring'E8 will then iorce the insulated part E7 el the lever B5 from theswitch E4, thus breaking the circuit through said switch E2, whichdenergizes the magneticsolenoid E3, and this releases the metal pin B7fromgits magnetic .in-l

fluence, permitting the arm B5 -of, thebellcrank lever B to moveinwardly bylineans of the spring E10.V This will force into contact thewheels E' E2 with the bands D2l D3. While this operation takes place theendE7 of1 the lever B closes the switch E", thereby lowing the currentto 'flow through thewire 9 to the wheel E2, to the band D3, throughthemagnetic wire D4 to the metallic band D2,

out through the wheel E', thence to the ground by the wire 10. Asexplained, the 7 metallic clutch memberD' will. by itsmagnetic influenceexert an attraction onthe'- lower clutch member D upwardly, .bringingIOO into contact the inclined surfaces of each member and holding theclutch in engagement, and thereby rotating the gearC,which will transmitpower to the gear C2, fast on the spindle C2, rotating said s indie towind up the chain C4 and set the rakes.y Thegear` C2 being of larger`diameter than the gear C" causes a multiplication of ower in theapplication oi the brakes. if t e spring E8 should become broken orotherwise lose its tension, the o erator can press on the outer end ofthe treay E5 of the lever B6 and causethe engagement of the end E7 withthe switch-E2. With the brakes applied, as above described, the o eratorcan open the motor-circuit, keeping t e clutch members engaged, and thebrakes nwill be automatically held by the ratchet or dog mechanism K5K6, located in the cap. K,

W'hen desired to release the In the diag,` fimmatic view, Fig. 12, thereis shown a pluv ility of solenoids and clutch members in .circuit fortrain-service, and the construction shown is embodied in the brakingapparatus on each end of the'cars in Figs. 1 to 9. f To energize the twosolenoids of one car or more in a train, the switch E4 is closed by theoperator, as above described, which closes the circuit through the Wire7- and solenoids E3, and the current passes by the wire 8 to the ground.The continuation of the current to thel next car is 4through the kwire Sand coupling connection S, thence tothe next car connected with thewires 7 and S through the solenoids E3,.thence to the Wire 8 to theground. In this manner the operation of the ,apparatus by the operatorat the head of a train releases the brakes by rotating the spindles, due.to the usual 4brake-spring .pull throughout the entire train by meansofthe electromagnetic solenoid-circuit in a manner similar tothatpreviously described for one car.

To apply the brakes by the rotation of the brake-spindles, the switch E4.is opened, which denergizes the solenoids, and -the switch E9 is closed,-which energizesl the mag# 'netc clutch, attractin .the clutchmembers to engagement, which c utch members are rotated by themotor-shaft C, which has been previously put in rotation,asvhereinbefore described. The source of current for the Wire-.circuitfor one or all of the clutch members is-similar to thesolenoid-circuit-that is, the source of supply comes from the Wire 7through theI switch E9 and -wire 9 through each upper clutch member Dout to the ground by the wire 10.

The electric circuit for the'clutch members for one or a train of carsis by means of the wire T and, coupling T.

Having described the circuits for the solenoid Vand the clutches, themotorcircuit (shown in diagrammatic view, Fig. 13 )will be described.The wiring for the motor-circuitv is las follows: The source' of supplyis from the wire 3, which is a. continuation of the Wires 1 2, and themanner of starting thc mojtor or motors is by throwing the arm N8 tocover the posts RR which will allow current to flow through the motor ormotors, as

shown by the wiring, and out to the ground.

by the wires 6.. U is'a coupling' placed between the cars fortrain-'service and with the wires U'carries the current through thetrain.

To the end .sill d and side sill ethe end frame and side frame of the car are secured in the usual mannerof car-building. gis the main brake-rod, and at one end of said rod isconnected the brake-chain C4, and the other end is pivotally connectedto vthe center brake-lever h. The main or center brake-lever. h issupported by the buacket t, secured to the bottom ofthe car, and has anequalizing-slot The said brake-lever hV is' held in place by the pin' c.

Pivotally connected-to the center brake-lever ward and are connected `t0similar mechanism at the right-handend ofthe car.` The operation of thismechanism is as follows:

By rotating the spindle Caz and winding up the 'chain C4 the brake-rod gvwill be pulled forward, thereby actuating the brake-lever h. This willpull in the opposite direction the secondary rods Z, and by `thisoperation the secondary rods will pull the truck-levers m toward thecenter'of the car, pressing out the bottom end of the levers m towardthe end of the car, causing the brake-beams p to travel inthe oppositedirection, and thereby apply the brake-shoes'to the-wheels. By thearrangement of the spindle with the brake-handle, as hereinbeforedescribed, the spindle can revolve in either direction Without rotatingthe handle, or the handle can be rotated in either direction withoutrotating the spindle or motor, or, if desired, the handle can rotate thespindle without rotating the motor or operate both at the same time. Tolrotate the motor-armature Without current, the clutch member D isbrought into engagement with the clutch member D by the foot-leverarrangement, so that by the rotation of the. 1 handle when the clutchmembers are engaged the gear becomes operative from the spindle to thearmature-shaft, thereby enabling the same to be rotated.
